PAVING-B LOOK.

Speeification` of Letters Patent.

Patented Nov. 12, 1907.

Application filed January 23. 1907. Serial No. 353.595.

To all whomit may concern:

Be it known that I, ALEXANDER KELLEY, a citizen of the United States`residing at l/VilmingtonV county of Newcastle, and State of Delaware,have invented a certain new and useful Improvement in Paving-Blocks, ofwhich the following is a specification.

My invention relates to a new and useful improve- Inent in pavingblocks,` and has for its object to provide a simple and effective blockwhich will fit into the flange of a street railway rail so that the railwill sustain the pressure put upon the blocks fitted therein, thuspreventing thesagging down of the blocks and maintaining an even'surfacewith the surface of the rails.

Another advantage of my invention is to make these blocks interlockingand reversible, so that when one surface has Worn they may be reversedand relaid, presenting a new wearing surface.

With these ends in view, this invention consists in the details ofconstruction and combination of elements hereinafter set forth and thenspecifically design-ated by the claims.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, I Will describeits construction in detailV referringl by letter to the accompanyingdrawing forming a part of this specification7 in which- 4 Figure 1 isa'perspective of a portion of a street railway track showing my iinprovedblocks fittedthereto. Fig. 2 is a detail perspective view of my improvedpaving block showing the groove to permit the passage of the stay red.-

Referring to these drawings E represents one form of my improved pavingblock7 which has formed therewith the tongue E'. adapted to fit betweenthe base and top flanges of the rail` as clearly shown in Fig. 1,forming a firm support for the block, so that the weight of vehielesupon the upper surface of the blocks will not cause them to sag, and astheir upper surface will be maintained on a level with the top flangesof the rail,

Vehicles may pass over the rails without the jar and twisting which isoccasioned when the ordinary paving blocks sag down below the surface ofthe rails.

rl`he blocks may have grooves F. formed in their ends so as to permitthe passage of the stay rods between the rails.

By the use of my improved block the upper inner flange of a railway railmay be made considerably less in width than those now in use, since theblock being flush therewith will serve the purpose of permitting wagontraction without the neeessit y of using the wide flange and thus saveconsiderable weight and cost of the rails.

Where a branch line or switch runs into the main line a block of theshape at MV in Fig. 1 may be used both sides of which would have tonguesformed thereon for fitting between the flanges of each rail.

M'y improved paving blocks are made of any suitable material that may bemolded or cut such as stone or cement.

Of course l do not wish to be limited to the exact contour of theblocks, as the gist of my invcntion rests in the broad idea of providinga block having a tongue central of the body adapted to fit between theflanges of a rail so as to bringthe surface of the block flush with theupper surface of the rail and receive a support from the bottom flangeof said rail.

Having thus fully described my invention, what I claim as new anduseful. is-

In combination with the rails of a street railway a paving' block havinga tongue formed therewith adapted to fit between the flanges of the railand a groove formed in its end adapted to cooper-ate with a similargroove in an adjacent block and a rod to pass through said groovcs asspecified.

In testimony whereof, I have hereunto afiixed my signature in thepresence of two subscribing witnesses.

ALEXANDER KELLEY.
